The Geological Survey of Canada owns and operates slim hole geophysical sondes and recording equipment for use in PVC cased boreholes in unconsolidated overburden. Such holes are commonly drilled and cased for overburden stratigraphic or geotechnical studies related to on-going GSC projects....

The GSC obtained access to industry-owned seismic reflection data along two profiles crossing volcanic rocks of the Noranda mining camp. The integration of seismic data and 3-D geological provides new constraints on the deep geological framework.

In 1991, 19 km of seismic reflection data and 20 km of deep-probing electromagnetic (EM) sounding data were acquired along a common corridor in the vicinity of the Thompson mine to help constrain the interpreation of sub-surface geological structures.

The specific objectives of this project are to: 1) investigate the feasibility of DSI techniques for delineating geological contacts in the Normetal area, with a view toward more extensive application of this method for exploration in the future; 2) characterize the seismic response of an...

A magnetotelluric survey in the Cumberland Peninsula consisting of 26 sites undertaken during the summer of 2009 in conjunction with bedrock mapping, has provided preliminary images of the subsurface geometries of the major geological boundaries and crustal-scale architecture.

An audio-magnetotelluric (AMT) survey performed under the supervision of the Geological Survey of Canada studied shallow and intermediate depth structures in the Nipigon region. The AMT survey successfully imaged the contact between the overlying Sibley Group sedimentary rocks and the Archean...

In 1987 the Geological Survey of Canada undertook a major regional seismic refraction survey in the Mackenzie Delta and surrounding area in order to complement existing data with information on the velocity structure of the crust and upper mantle. The survey consisted of seven recorder...
